DESCRIPTION OF EXAMPLE EMBODIMENTS

Example embodiments of this application provide a content presenting method, so that video content can be intuitively presented in a 3D application without additionally opening a small window by a user, improving video content presentation quality, and also improving efficiency of communication between the user and an interactive application and the video content. The example embodiments of this application further provide corresponding user equipment and a corresponding system. Detailed descriptions are separately provided below.

The following clearly and completely describes the technical solutions in the example embodiments of this application with reference to the accompanying drawings in the example embodiments of this application. Apparently, the described example embodiments are some example embodiments of this application rather than all of the example embodiments. All other example embodiments obtained by a person skilled in the art based on the example embodiments of this application without creative efforts shall fall within the protection scope of this application.

For ease of understanding, the following first briefly describes terms in this application.

A 3D application system in the example embodiments of this application may be understood as a 3D game system.

A 3D game is a stereoscopic video game manufactured based on 3D computer graphics, including, but not limited to: an online 3D game in which multi-players are online, a single player 3D game in which a single player plays a game, and a virtual reality game system established based on a 3D game system. The 3D game is suitable for use in platforms, such as a video game console, a mobile phone game platform, and a personal computer game platform, 3D games on which are all included.

A virtual community is a virtual community environment of a 3D game, and is a game environment manufactured based on 3D computer graphics. The virtual community may include a simulated object corresponding to a player in the game. The virtual community in this application includes a virtual screen, and the virtual screen may be similar to a large virtual screen projected in the external field.

A game anchor is a person that reports and narrates a game on electronic media such as the Internet.

A live game broadcast means broadcasting while playing a game by using an Internet technology.

Using League of Legends (LOL) as an example, a browser is usually built in a game client, and the browser enables a player in the game client to watch a real-time live video and perform simple interaction. However, the concept of virtual community is not included in this product and game players cannot directly perceive the existence of each other. This solution is much more similar to watching a competition in front of a television, but the solutions provided in this application are mainly to create an atmosphere of watching a competition on live.

The example embodiments of this application describe a solution of combining a 3D simulated virtual community with a live video on the Internet, and the solution provided in the example embodiments of this application enables a player to watch, in the simulated virtual community, a live video on the Internet.

A live video on a virtual screen of the virtual community may be a video broadcasted by a game anchor, or may be another live game video. For an example of the virtual community or a 3D application scenario in the example embodiments of this application, refer to FIG. 1 for understanding.

FIG. 2 is a schematic diagram of a 3D application system according to example embodiments.

As shown in FIG. 2, the 3D application system includes a 3D application server, a content providing server, and a plurality of user equipments. Each user equipment may correspond to one player, and each user equipment has installed a client of a 3D application.

The player clicks, on the user equipment, the client of the 3D application, and the user equipment starts the 3D application in response to an instruction for starting the 3D application. The 3D application includes a simulated object and a virtual screen for watching video content by the simulated object, and the simulated object in the 3D application may be a virtual identity of the player in the 3D application.

In a procedure of starting the 3D application, the 3D application requests, from the 3D application server, an address of live content that is currently broadcasted on the virtual screen, that is, a content source address in these example embodiments of this application. The 3D application server sends the content source address to the user equipment after determining the content source address according to the live content that is currently broadcasted.

The user equipment obtains audio and video data from the content providing server according to the content source address after receiving the content source address, and the audio and video data is audio and video data of the live content.

The user equipment renders the audio and video data after obtaining the audio and video data of the live content, to obtain corresponding audio content and video content, and plays the audio content in the 3D application and displays the video content by using the virtual screen.

FIG. 3A is a schematic diagram of a content presenting method according example embodiments.

For a method for presenting a live video in a 3D application, refer to a procedure of FIG. 3 for understanding.

101. User equipment starts a 3D application in response to an instruction for starting the 3D application.

The 3D application includes a simulated object and a virtual screen for watching video content by the simulated object.

102. The user equipment receives a content source address sent by the 3D application server, and sends the content source address to a content providing server.

The content source address is an address of live content that is currently broadcasted on the 3D application server.

103. The user equipment obtains audio and video data from the content providing server according to the content source address.

The audio and video data is audio and video data of a game that is currently played on a game server or of other video content.

104. The user equipment renders the audio and video data to obtain video content and audio content.

105. The user equipment plays the audio content in the 3D application, and displays the video content by using the virtual screen.

A small window may need to be used to display other video content when a 3D application is displayed. By comparison, according to the content presenting method provided in the example embodiments of this application, video content can be presented on a virtual screen of a 3D application without additionally opening a small window by a user, improving video content presentation quality, and also improving efficiency of communication between the user and an interactive application and the video content.

Optionally, the audio and video data includes audio data and video data, and the rendering the audio and video data to obtain video content and audio content includes:

rendering, by the user equipment, the audio data by using a web page process to obtain the audio content, and rendering the video data by using the web page process to obtain the video content; and

the playing, by the user equipment, the audio content in the 3D application, and displaying the video content by using the virtual screen includes:

playing, by the user equipment, the audio content by using a process of the 3D application, and displaying the video content on the virtual screen by using the process of the 3D application.

In these example embodiments of this application, the audio data and the video data are rendered by using the web page process, and then are displayed by using the process of the 3D application, so that a page rendered by the web page process is extracted by cross-process communication when web page rendering data is required for the process of the 3D application. The process of the 3D application and the web page process can be separated by such processing, increasing stability of the process of the 3D application.

Further, the video image data includes a plurality of image frames, and the rendering the video data by using the web page process to obtain the video content includes:

determining differential content between an (N+1)th image frame and an Nth image frame when the user equipment renders the (N+1)th image frame by using the web page process, and rendering only the differential content when rendering the (N+1)th image frame, where N is an integer greater than 0.

In these example embodiments of this application, during image frame rendering, repeated content is no longer rendered again, and only differential content between two consecutive frames is rendered, reducing bandwidth consumption of a graphic processing unit (GPU), and improving program execution efficiency and user experience.

Further, before the displaying the video content on the virtual screen by using the process of the 3D application, the method further includes:

performing, by the user equipment, inverse gamma correction on texture of the video content once; and

the displaying the video content on the virtual screen by using the process of the 3D application includes:

displaying, by the user equipment on the virtual screen by using the process of the 3D application, video content on which inverse gamma correction has been performed.

In these example embodiments, used maps are maps on which gamma correction has been performed, and if the gamma correction is not performed, an operation result may be incorrect. In this case, image data submitted from another thread has been corrected, and a color cast may occur if the image data is directly put in a high-end rendering pipeline. Therefore, inverse gamma correction is performed on the texture of the video content once.

Further, before the playing, by the user equipment, the audio content by using a process of the 3D application, the method further includes:

introducing, by the user equipment, the audio content into a coordinate system of an interactive application to which the simulated object belongs, and determining audio intensity of the audio content at different coordinate points; and

the playing, by the user equipment, the audio content by using a process of the 3D application includes:

playing, by the user equipment at the different coordinate points, the audio content according to the audio intensity corresponding to the coordinate points.

Audio playing intensity of different coordinate points is different; therefore, audio is introduced to the coordinate system, to produce a stereophonic effect.

Further, for the obtaining, by the user equipment, audio and video data from the content providing server according to the content source address, the method further includes:

obtaining, by the user equipment, content of interaction between an anchor of the video content played on the virtual screen and the simulated object; and

for the displaying the video content by using the virtual screen, the method further includes:

displaying, by the user equipment, the interaction content by using the virtual screen.

The content of interaction between the anchor and the simulated object may be displayed by using the virtual screen, increasing interaction between a user and the anchor.

Further, the method further includes:

displaying, at a position of the simulated object, content of interaction between the simulated object and another simulated object.

In a relatively real recreational zone, players in the 3D application have respective game roles. The roles may talk with each other, and make exemplary actions. Players in a same recreational zone may watch the same content, and have a same topic. As shown in FIG. 3B, a conversation, “what would you like to drink?”, that is made by a simulated object with another simulated object may be displayed nearby the simulated object.

A 3D application scenario is broadcasting live game content on a large screen by a game anchor when playing a game. For such a scenario related to an anchor, FIG. 4 is described below.

FIG. 4 is a schematic diagram of another example of a 3D application system according to example embodiments.

As shown in FIG. 4, the 3D application system further includes user equipment used by an anchor. The anchor broadcasts a live game by using the user equipment, and a live game video stream is uploaded to a content providing server. The anchor has registered with a game server in advance; therefore, the game server stores a source address of live content that is currently broadcasted. A player may further interact with the anchor. Therefore, a live broadcasting procedure may further include content of interaction between the anchor and a simulated object. Therefore, user equipment may obtain the live video stream and the interaction content from the content providing server.

The user equipment renders audio and a video after obtaining the live video stream and the interaction content, to obtain corresponding audio content and video content, and plays the audio content by using a 3D application and displays the video content and the interaction content by using the virtual screen.

The following describes, with reference to FIG. 5, a content presenting method in a scenario including an anchor that performs live broadcasting.

FIG. 5 is a schematic diagram of an example embodiment of a content presenting method according to example embodiments.

201. An anchor broadcasts a live video on the Internet, and the anchor submits, to a content providing server by using user equipment, a live video stream broadcasted by the anchor.

202. After a user opens a 3D application program on a corresponding user equipment, the program starts to initialize a 3D rendering engine in a 3D application.

203. The program starts to automatically request a video source address of the anchor currently performing live broadcasting.

204. A 3D application server delivers the video source address to an audio and video rendering module of the corresponding user equipment.

205. The audio and video rendering module requests a data stream of the live video from the content providing server.

206. A live video server returns a video data stream to the audio and video rendering module.

207. The audio and video rendering module renders audio by using audio and video data.

208. The audio and video rendering module submits audio data to an audio engine in the 3D application.

209. The audio and video rendering module renders a video single-frame image by using the audio and video data.

210. The audio and video rendering module submits image data to the 3D rendering engine in the 3D application.

211. The rendering engine performs rendering in a 3D world by using rendered static frame data, plays audio content, and presents a video picture to the user.

For an image rendering procedure of step 209, it may be understood that because a flash technology frame is generally used for a live video on the Internet, and a used flash plug-in has a plurality of uncertain issues, another independent process is used in this application for rendering a web page, to prevent the flash plug-in from affecting stability of a game. The game may only need to extract a web page to be rendered by cross-process communication when web page rendering data is required. A game process and a web page rendering process can be separated by such processing, increasing stability of the game process.

For a cross-process image rendering procedure, refer to FIG. 6 for understanding.

FIG. 6 is a schematic diagram of cross-process image rendering according to example embodiments.

The cross-process image rendering process is divided into two processes: a game rendering process and a web page rendering process. A rendering procedure of the two processes may be performed by the user equipment, and include the following steps:

20911. Perform a game rendering process.

20921. Perform a web page rendering process.

20922. Initialize rendering.

20912. Enter a main loop of a game.

20913. Start rendering.

20914. Render game content.

20915. Check whether Internet video stream rendering exists; and perform step 20923 if an Internet video stream rendering exists, or perform step 20917 if no Internet video stream rendering exists.

20923. Wait for a game process rendering message.

20924. Detect whether a dirty page currently exists; and perform steps 20925 and 20926 if a dirty page currently exists, or perform step 20927 if no dirty page exists currently.

Checking a dirty page means checking whether there is a content difference between two image frames, and differential content is a dirty page if there is a content difference between the two image frames.

20925. Update the dirty page.

20926. Format an updated page into a format available for the game.

For a procedure of updating a dirty region, refer to FIG. 7 for understanding.

FIG. 7 is a schematic diagram of dirty region update according to example embodiments.

A dirty region of a web page image buffer in a central processing unit (CPU) is updated, to obtain a dirty region in video random access memory (RAM) texture in an image processing unit or graphics processing unit (GPU).

Referring again to FIG. 6, the rendering procedure of the two processes may include the following steps:

20927. Directly return if no dirty page exists.

20928. Complete web page rendering.

20916. Combine game content and web page content.

20917: Complete the rendering.

The main loop of the game may be entered again, to repeat the loop.

The method for updating a dirty region may reduce bandwidth consumption of a GPU, and improve program execution efficiency and user experience.

Image data of Internet video rendering can be obtained after the foregoing steps are performed, but the data cannot be directly used in final rendering. The following focuses on the description of step 211.

A modern graphics engine tends to have a plurality of rendering pipelines, to satisfy different image quantity requirements.

FIG. 8 is a schematic diagram of an example of a web page according to example embodiments. FIG. 9 is a schematic diagram of an example of a web page with an added virtual screen according to example embodiments. FIG. 10 is a schematic diagram of an example of a web page with an added virtual screen after inverse gamma correction according to example embodiments.

For example, in a high-end rendering pipeline, used maps are maps on which gamma correction has been performed, as shown in FIG. 8. If the gamma correction is not performed, an operation result may be incorrect. In this case, image data submitted from another web page process and obtained in the game process is image data on which gamma correction has been performed, and a color cast may occur if the image data is directly put in the high-end rendering pipeline. For example, as shown in FIG. 9, a color of a picture in FIG. 9 is obviously darker than a color of a picture in FIG. 8, and a color cast occurs.

A browser component obtains, by rendering, a texture on which gamma correction has been performed once, and may need to perform inverse gamma correction once first to obtain linear color space. Then, a picture without a color cast shown in FIG. 10 can be obtained.

For compatibility issues of high-end, middle-end, low-end machines, because a broadcasting screen does not need to be exposed to light, an inverse gamma correction may only need to be performed once, resulting in relatively low rendering consumption. Therefore, the foregoing processing procedure can be used for all of the high-end, middle-end, low-end machines.

A procedure of presenting a video image in a 3D application is completed after the foregoing steps are performed, the following describes output and processing of audio information, that is, focuses on the description of step 207.

FIG. 11 is a schematic diagram cross-process audio rendering according to example embodiments.

The cross-process audio rendering may be performed by the user equipment, and may include the following steps:

20711. Perform a game rendering process.

20721. Perform a web page rendering process.

20712. Enter a main loop of a game.

20722. Initialize a web page sound interface.

20713. Prepare sound content of the game.

20714. Check whether a web page sound requirement exists; and perform step 20723 if a web page sound requirement exists, or perform step 20716 if no web page sound requirement exists.

20723. Wait for a game process to read sound data.

20724. Extract a current sound data stream.

20725. Convert a format of the data stream into audio data.

20726. The web page rendering process ends.

20715. Put a web page sound source into a 3D coordinate system.

20716. Perform sound synthesis.

The main loop of the game may be entered again, to repeat the loop.

After step 20716, the game may end.

By analyzing a sound interface of a web page rendering engine, this application configures a sound interface applicable to systems such as XP and win7. A data steam may be exported by using the interface, and the obtained data stream may be configured into a 3D coordinate system of a 3D game. In this way, a simulated object of a player may perceive different audio intensity when the simulated object stands at different positions in the game. By the foregoing method, a stereophonic sound effect is implemented.

This application implements a function of playing an Internet video stream in a 3D game, and combines a recreation game with an Internet video, so that a player can watch a favored video program while playing a game, resolving a problem of frequently switching between a browser and the game for the player, and providing intuitive experience in which players watch a competition together, thereby greatly improving game experience of the player.
